M2006-02A
VCSO BASED FEC CLOCK PLL
Product Data Sheet
GENERAL DESCRIPTION
The M2006-02A is a VCSO (Voltage Controlled SAW
Oscillator) based clock generator
PLL designed for clock frequency
translation and jitter attenuation.
The device supports both forward
and inverse FEC (Forward Error
Correction) clock multiplication
ratios. Multiplication ratios are
pin-selected from pre-programming look-up tables.
FEATURES
◆ Reduced intrinsic output jitter and improved power
supply noise rejection compared to M2006-02
◆ Low phase jitter of 0.25 ps rms typical
(12kHz to 20MHz or 50kHz to 80MHz)
◆ Pin-selectable PLL divider ratios support forward and
inverse FEC ratio translation, including:
255/238 (OTU1) Mapping and 238/255 De-mapping
255/237 (OTU2) Mapping and 237/255 De-mapping
255/236 (OTU3) Mapping and 236/255 De-mapping
◆ Input reference and VCSO frequencies up to 700MHz,
supports loop timing modes
(Specify VCSO frequency at time of order)
◆ Supports active switching between inverse-FEC and
non-FEC clock ratios (same VCSO center frequency)
◆ Ideal for complex ratio FEC ratio translation and
for use with an unstable reference (i.e., similar to the
M2006-12A - and pin-compatible - but without the
Hitless Switching and Phase Build-out functions)
◆ Single 3.3V power supply
◆ Small 9 x 9 mm SMT (surface mount) package
